Today Ati launched the HD 5800 graphics card series. PC Games Hardware has reviewed the Radeon HD 5870 and checked the performance of the first DirectX 11 graphics card in several games like Crysis Warhead, Stalker: Clear Sky, GTA 4 and Fallout 3. We also dealt with the temperatures, noise and power consumption of the card as well as the overclocking capabilities. Furthermore we took a look at the improved Anisotropic Filtering and the supported Supersampling Anti Aliasing.
